STEPWISE ETHANOL-WATER FRACTIONATION OF ENZYMATIC HYDROLYSIS LIGNIN TO IMPROVE ITS PERFORMANCE AS A CATIONIC DYE ADSORBENT

Stepwise Ethanol-Water Fractionation of Enzymatic Hydrolysis Lignin to Improve Its Performance as a Cationic Dye Adsorbent

In this work, lignin fractionation is proposed as an effective approach to reduce the heterogeneity of lignin and improve the adsorption and recycle performances of lignin as a cationic dye adsorbent.By stepwise dissolution of enzymatic hydrolysis lignin in 95% and 80% ethanol solutions, three lignin subdivisions (95% ethanol-soluble subdivision, 8
